4.
Adjust the gain pot (P100 for channel 1, P200 for channel 2, P300 for channel 3,
and P400 for channel 4) so that the DVM indicates a “resistance” of 500
Ω
.
5.
Verify that the offset was nulled by connecting the current source from the DVM
to the input of the other channel and measuring a resistance of less than 1
Ω
.
6.
Repeat the gain adjustment for the second channel.
